PROJECT DETAILS
Denso were asked to provide a solution to protect threaded bars which are used to secure an above ground pipeline of roughly 23km which consists of 3893 pedestals and 7786 threaded round bars. The M20 threaded bar, as well as the nut, is hot-dipped galvanised however, being exposed to the elements and taking into consideration the corrosive environment surrounding Swakopmund, further protection is required.
Denso proposed and trialed the Steelcoat™ ColourTape in the presence of the client, consultant and contractor in October 2021 and, after three months of subjecting the ColourTape to the harsh environments of Namibia, it was removed from the threaded bars to reveal a corrosion-free bar.
Based on this performance, we received the order to protect all 7786 threaded bars and we have also been written into the Namwater specification.
